我正面临 dotNET 核心应用程序的这个问题，它使用 odbc.ini 中定义的 DSN 与 SQL 服务器连接和断开连接。目前我正在使用最新的 MS SQL ODBC 驱动程序，即 msodbcsql17-17.4.2.1-1 和 UnixODBC 驱动程序 unixODBC 2.3.7。
我也尝试将 MSSQL ODBC 驱动程序降级到 11 和 13，但都没有成功。
我当前来自 odbc.ini 的 DSN 设置如下：
[ICMDB]
Driver = /opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.4.so.2.1
Server = 10.32.7.145
Port = 1433
User = user
Password = password
Database = inst3_sideA
Language = us_english
和日志文件包含以下错误：
